In the center of the main body 101 of the slot machine 100 shown in FIG. 1, three reels (a left reel 110, a middle reel 111, and a right reel 112) having a plurality of types of patterns arranged on the outer peripheral surface are stored. It is configured to be able to rotate inside. These reels 110 to 112 are rotationally driven by a driving means such as a stepping motor (not shown). In this embodiment, an appropriate number of each pattern is printed on the belt-like member at equal intervals, and the reels 110 to 112 are configured by sticking this belt-like member to a predetermined circular frame material. When viewed from the player, approximately three patterns on the reels 110 to 112 are displayed in the vertical direction from the pattern display window 113 so that a total of nine patterns can be seen. Then, by rotating each of the reels 110 to 112, the combination of pictures that can be seen by the player varies. That is, each of the reels 110 to 112 functions as a display unit that displays the pattern combination in a variable manner. As such a display means, an image display device such as a liquid crystal display device can be employed in addition to the reel. In this embodiment, three reels are provided in the center of the slot machine 100, but the number of reels and the installation position of the reels are not limited to this.

  A backlight (not shown) for illuminating each picture displayed on the picture display window 113 is disposed on the back of each reel 110 to 112. It is desirable that the backlight is shielded for each pattern so that each pattern can be illuminated evenly. In the slot machine 100, an optical sensor (not shown) including a light projecting unit and a light receiving unit is provided in the vicinity of each of the reels 110 to 112.

  The liquid crystal display device (LCD) 180 can display various information related to the game (effect information that excites the game, error information that displays the content of an error when an abnormality occurs in the slot machine, and the like). Of course, instead of the liquid crystal display device 180, other display means such as a dot matrix type display device in which a plurality of LEDs are two-dimensionally arranged may be used.

<Start lever unit>
Next, the structure of the start lever unit 200 will be described with reference to FIGS. 2 (a) to 2 (d). The configuration of the start lever unit 200 is basically the same as the configuration of the start lever unit conventionally used. As shown in FIGS. 2A, 2C, and 2D, the start lever unit 200 detects the start lever 201, the support frame 206 that supports the start lever 201, and the start operation for the start lever 201. And a start lever sensor 210 as means.

  The start lever 201 is provided at one end of the spherical operation unit 201a operated by the player and the other end, and the start lever sensor 210 detects a start operation. A light shielding member 201c, and a movable shaft 201b that couples the operation unit 201a and the light shielding member 201c.

  The support frame 206 is formed in a substantially cylindrical shape so that the movable shaft 201b of the start lever 201 can be inserted therethrough, and includes a shaft body 207 that passes through the movable shaft 201b so as to be orthogonal to the movable shaft 201b. It is supported so as to be rotatable around 207. As shown in FIGS. 2C and 2D, a disc-like stopper 214 that abuts against a shoulder 213 formed on the inner peripheral wall of the support frame 206 is loosely fitted on the movable shaft 201b. A coil spring 216 that constantly urges the movable shaft 201b to a neutral position is loaded between 214 and a spring receiver 215 fixed to the movable shaft 201b. Then, when the player pushes down the operation portion 201a, the start lever 201 is urged by this and rotates as shown in FIG. 2 (d), but this causes the coil spring 216 to be compressed. When the operation on the portion 201a is finished, the start lever 201 returns to the neutral position shown in FIG.

  As shown in FIG. 2B, in this embodiment, the start lever sensor 210 includes an optical sensor including a light emitting unit 210a that emits light and a light receiving unit 210b that receives light emitted from the light emitting unit 210a. Has been. In this embodiment, an optical sensor is employed as the start lever sensor 210, but other sensors are also applicable. The light emitting unit 210a and the light receiving unit 210b are arranged to face each other. As shown in FIG. 2C, when the start lever 201 is in a neutral position (when the player does not operate the start lever 201), the light shielding member 201c is formed between the light emitting unit 210a and the light receiving unit 210b. Located in the gap between them, the light receiving unit 210b cannot receive light from the light emitting unit 210a. On the other hand, when a start operation is performed on the start lever 201 and the start lever 201 is rotated as shown in FIG. 2D, the light shielding member 201c is thereby positioned at which the light receiving unit 210b can receive light from the light emitting unit 210a. Will be moved to.

<Control unit>
Next, the configuration of the control unit of the slot machine 100 will be described with reference to FIG. The control unit in the present embodiment controls a main control unit 300 that controls the entire slot machine 100, a sub-control unit 400 that performs control related to effects for exciting games, and a liquid crystal display (LCD) 180. And a liquid crystal display control unit 500.

<Main control unit 300>
The microprocessor (hereinafter referred to as “Main CPU”) 310 serves as a center of control in the slot machine 100, and exchanges control signals and data with peripheral units via the bus 370. The random number generation circuit 311 generates a cyclically updated numerical value (hereinafter referred to as a random number value), and includes a plurality of counters, a clock oscillator, a frequency divider, a latch circuit, and the like. The random number value generated by the random number generation circuit 311 is acquired by the CPU 310 via the bus 370 as necessary.

  FIG. 4 is a diagram exemplarily showing the circuit configuration of the random number generation circuit 311. The random number generation circuit 311 includes two counter ICs 604 and 605. Each of these counter ICs 604 and 605 is an 8-bit binary counter, and based on a clock signal oscillated from a crystal oscillator (not shown), a numerical value for 16 bits, that is, a value from 0 to 65535 is periodically inputted. Count cyclically.

  Assuming that the frequency of the clock signal oscillated from the crystal oscillator is 14.31 MHz, the count value makes a round with a period of 4.57 ms. When the counter ICs 604 and 605 receive a latch signal from the outside (here, the start operation detection signal from the start lever sensor 210: START in the figure), the count value at that time is set as a random number value on each data bus. Output (determination of random value). More specifically, each counter IC 604 and 605 includes an internal register, and the count value is loaded into the internal register and latched at the rising edge of the signal with respect to the register clock (RCLK). When the enable input (G) is set to “Low”, that is, when a chip select signal is transmitted from the Main CPU 310 via the bus 370, the random value latched in the internal register is output on the bus 370, It can be acquired by the Main CPU 310. In this example, the random number value (count value) is overwritten and latched in the internal register every time the signal rises with respect to the register clock (RCLK). However, a plurality of random number values are not sequentially overwritten and latched. The latest random number value may be output when the chip select signal is transmitted.

  When a start operation (start operation) is performed on the start lever 201, this is detected by the start lever sensor 210, and a detection signal is output as a random number acquisition command to the input interface 365 described later. The Main CPU 310 reads the presence / absence of a detection signal from the input interface 365 in the above-described interrupt cycle, and if there is a detection signal, acquires the counter value latched in the counter ICs 604 and 605 as a random value. The acquired random number value is temporarily stored in the RAM 313 and used in the internal lottery of the winning combination.

  Returning to FIG. 3, the main CPU 310 receives the medal sensor 320 that detects a medal inserted from the medal insertion slot 134 via the input interface 365 and the bus 370, and the start lever sensor 210 that detects the start operation for the start lever 201. When any one of the stop buttons 137 to 139 is pressed, a stop button sensor 322 for detecting which stop button is pressed, and when any one of the medal insertion buttons 130 and 131 is pressed, which medal is inserted. A medal insertion button sensor 323 is connected to detect whether the button has been pressed.

  A ROM (read-only memory) 312 is one of storage means for storing programs for performing various controls, various table data to be described later, and the like. A RAM (Random Access Memory) 313 has a work area for programs processed by the Main CPU 310 and is one of storage means for storing variable data and the like. In the present embodiment, the ROM and the RAM are employed as described above, but it goes without saying that other storage means can be employed. This also applies to the sub-control unit 400 and the liquid crystal display control unit 500 described later. Further, a motor control unit 331 for controlling a motor (not shown) for rotating the reels 110 to 112 and a hopper control unit 332 for controlling a medal payout device (so-called hopper: not shown) are provided with an input / output interface 340 and The main CPU 310 is connected via a bus 370. A start lever sensor controller 333 that controls the operation of the start lever sensor 210 is also connected to the Main CPU 310 via the input / output interface 340 and the bus 370. Details of the start lever sensor control unit 333 and the start operation detection will be described later.

  The lamps 334 collectively represent lamps such as the winning line display lamp 120 shown in FIG. 1 and various displays such as the payout number display 125, and the Main CPU 310 via the output interface 350 and the bus 370. It is connected to the. The output interface 360 transmits various main control commands to the input interface 430 of the sub-control unit 400 based on instructions from the Main CPU 310.

<Sub-control unit 400>
The microprocessor (hereinafter referred to as SubCPU) 410 receives various commands transmitted from the main control unit 300 via the input interface 430 and the bus 460, and controls the sub-control unit 400 as a whole according to the contents of the received commands. To do. The ROM 411 is one of storage means for storing programs and data for controlling the sub-control unit 400 as a whole. The RAM 412 has a work area for programs processed by the SubCPU 410, and is one of storage means for storing variable data and the like. The lamps 413 collectively represent a backlight or the like that illuminates the picture of the reel from the back. The lamps 413 are connected to the SubCPU 410 via the output interface 420 and the bus 460, and are turned on / flashing / turned off according to instructions from the SubCPU 410.

  The tone signal forming unit 450 forms a tone signal based on the control signal and data delivered from the SubCPU 410 and outputs the tone signal. The musical sound signal is amplified by the amplifier 451 and then output as a sound from the speaker 462. The output interface 440 transmits various control data to the liquid crystal display control unit 500 based on an instruction from the SubCPU 410. Based on this control data, the liquid crystal display control unit 500 controls the liquid crystal display device 180.

<Liquid crystal display controller 500>
Next, the liquid crystal display control unit 500 of the slot machine 100 will be described. The liquid crystal display control unit 500 includes a microprocessor (hereinafter referred to as LCD CPU) 510, a data bus and an address bus for transmitting and receiving signals to and from each IC and each circuit, and has a configuration described below. The LCD CPU 510 receives a signal from the Sub CPU 410 output via the output interface 440 of the sub-control unit 400 via the input interface 530 and the bus, and controls the entire liquid crystal display control unit 500. The ROM 511 stores programs and data for controlling the entire liquid crystal display control unit 500. Further, a VDP (video display processor) 550 is connected to the LCD CPU 510 via a bus. A ROM 552 is connected to the VDP 550. The ROM 552 stores a program processed by the VDP 550. An LCD 180 is connected to the VDP 550 via an output interface 553, and display control of the LCD 180 is performed.

<Detection of start operation>
FIG. 5 is a diagram schematically illustrating the operation of the start lever sensor control unit 333. The start lever sensor control unit 333 is a drive circuit that drives the light emitting unit 210 a of the start lever sensor 210, and controls the light emission according to a command from the Main CPU 310. The light receiving unit 210b outputs the light reception signal of the light from the light emitting unit 210a to the input interface 365 as the sensor output of the start lever sensor 210.

  Here, in the present embodiment, the operation state of the start lever sensor 210 is alternately changed between a detectable state where the start operation on the start lever 201 can be detected and a non-detection state where the start operation is not detected. In the present embodiment, the light emitting unit 210a is pulse-driven to blink at a predetermined cycle. When the light emitting unit 210a is turned on, it is in a detection state, and when it is turned off, it is in a non-detection state.

  FIG. 6 is a timing chart illustrating how the start lever sensor 210 detects the start operation and its detection principle. 6, (a) is a clock signal transmitted from the crystal oscillator of the random number generation circuit 311, (b) is a timing chart of numerical value update of the random number generation circuit 311 (synchronized with the clock signal of FIG. 6 (a)), c) is a drive pulse input from the start lever sensor control unit 333 to the light emitting unit 210a, (d) is an example of sensor output output from the light receiving unit 210b, and (e) is an example of detection timing of the start operation. ing.

  In the case of the present embodiment, the light emitting unit 210a starts blinking from the time when the start operation for the start lever 201 can be accepted, and is turned off until then. 6A shows the timing when the start operation for the start lever 201 can be accepted, that is, the blinking start timing of the light emitting unit 210a. In this embodiment, the start operation for the start lever 201 is accepted when a medal is inserted. The reason for setting the blink start time will be described later.

  The flashing cycle of the light emitting unit 210a is set such that, for example, 1. flashing is performed a plurality of times during the operation time (approximately several hundred ms) until the player starts and ends the start operation. 877 ms, which is a fixed period here. It is to be noted that the illegal action by the so-called sensation device is limited to aiming at a cycle of 5 ms at the shortest, so if the blinking is performed at a cycle of about 2 ms, a sufficient fraud prevention effect can be obtained. When the light emitting unit 210a starts to blink, the light receiving unit 210b can receive the light, but when the start lever 201 is in the neutral position, that is, when the start operation is not performed, the light shielding member 201c is moved from the light emitting unit 210a. Since the emitted light is shielded, the light receiving unit 210b does not receive the light.

  On the other hand, when the start operation is performed on the start lever 201 (B in FIG. 6), the light blocking member 201c does not block the light emitted from the light emitting unit 210a, and the light receiving unit 210b can receive light. However, even if the start operation is performed on the start lever 201, the start operation is not detected if the light emitting unit 210a is turned off, and the start operation is detected at the timing when the light emitting unit 210a emits light (C in FIG. 6). Will be. Therefore, the delay time 1 in FIG. 6 can be generated from the timing when the player performs the start operation until the start operation is detected. In the present embodiment, the start operation is detected at the rise of the light emission of the light emitting unit 210a. However, the start operation may be detected.

  Thus, in this embodiment, the operation state of the start lever sensor 210 is alternately changed between the detectable state and the non-detectable state by blinking the light emitting unit 210a. Therefore, the timing at which the start operation is detected (that is, the timing at which the random value acquired by the Main CPU 310 is determined) is when the start operation is performed and the start lever sensor 210 is in a detectable state. That is, the timing at which the random value is determined does not depend only on the timing of the start operation, and it becomes difficult for the player to influence the random value. Therefore, it is possible to prevent an act of illegally generating the internal winning of the winning combination. Further, since it is sufficient to change the operation state of the start lever sensor 210 alternately, the illegal act can be prevented relatively easily.

  In the present embodiment, as described above, the light emitting unit 210a starts blinking when the start operation for the start lever 201 becomes acceptable. In the present embodiment, the start operation can be accepted when a medal is inserted, which is irregular. Accordingly, the flashing start timing of the light emitting unit 210a is also irregular, and even if the player performs the starting operation in consideration of the flashing cycle of the light emitting unit 210a and the update cycle of the random number value, The lighting and unlighting states of the light emitting unit 210a are not constant, making it more difficult for the player to influence the random number value and further preventing fraud.

<Basic flow>
Next, a description will be given regarding control of the slot machine 100. FIG. 7 is a flowchart showing a game execution process which is a basic control of the game in the slot machine 100 of the present embodiment. When the power is turned on, various initialization processes are executed, and this game execution process is performed. The game execution process is performed mainly by the Main CPU 310, and is repeatedly executed unless a power shutdown or the like is detected. Hereinafter, this game execution process will be described. In step S101, medal insertion acceptance processing is performed. FIG. 8 is a flowchart of the medal acceptance process. In S121, the prescribed number is set. The prescribed number here means the number of medals that need to be inserted in the game. For example, the number is one for a so-called bonus game and three for other games such as a normal game. In S122, it is determined whether or not the number of inserted medals has reached the specified number set in S121. If applicable, the process is terminated, and a start operation for the start lever 201 can be accepted in S102 of FIG. If not applicable, it will be waiting.

  Returning to FIG. 7, in S102, start operation reception / random value acquisition processing is performed. Here, processing relating to detection of a start operation, acquisition of a random number value, and start of rotation of the reels 110 to 112 is performed. Details will be described later.

  Next, in S103, an internal lottery of a winning combination is performed using the random number value acquired in S102 and the winning combination lottery table stored in the ROM 312. As a result of the internal lottery, when any winning combination is won internally, the winning combination flag set in the RAM 313 is turned ON. Examples of the winning combination include the above-mentioned replay (replay), small combination, bonus (BB, RB), and the like.

  Each winning combination has a winning probability of internal lottery set for each bet number of medals and set values (1 to 6), and the winning combination lottery table is configured in accordance with this and is obtained at the time of the lottery. The numerical value range (for example, 0 to 16384) is divided in advance into several areas (areas corresponding to the size of each winning probability), and each area is associated with winning or losing of each winning combination. . In the internal lottery of the winning combination, whether or not the internal winning of the winning combination is successful is determined according to which range the acquired random number value belongs.

  Next, in S104, a reel stop preparation process for selecting reel stop control data is performed. This is a process of selecting a control for the stop operation of each reel. Here, the stop control of the reels 110 to 112 will be briefly described. The reel stop control is performed based on the selected reel stop control data by selecting any one of a plurality of predetermined reel stop control data based on the internal lottery result. The reel stop control data is stored in the ROM 312 of the main control unit 300. Reel stop control data is allowed to be displayed together for the winning combination that was won internally by the internal lottery or the so-called flag carryover winning combination, otherwise, It is configured so that the pattern combinations corresponding to each winning combination are not displayed together. For example, if the “bell” of the small role is not internally won, even if the reels 110 to 112 are stopped at the timing when the “bell” symbol combination is displayed, the reels 110 to 112 are stopped immediately. Therefore, control is performed so that the combination of bell patterns is not completed. On the other hand, when “Bell” is won internally, even if the reels 110 to 112 are not stopped at the timing when the bell picture combination is displayed, the reels 110 to 112 are within a certain range. It will be controlled so that the combination of the pattern of the bells is aligned without stopping immediately.

  Next, in step S105, effect lottery processing is performed. Here, based on the random value acquired in step S102, a lottery for determining the type of effect to be performed is performed. Next, in step S106, stop button reception processing that enables reception of the stop buttons 137 to 139 is performed. Here, when any one of the stop buttons 137 to 139 is pressed, in step S107, the reels 110 to 112 corresponding to the pressed stop button are stopped based on the reel stop control data acquired in S1008. In step S108, it is determined whether or not all reels are stopped. If not stopped (NO in step S108), the process returns to step S106. If all are stopped (YES in step S108), the process proceeds to step S109.

  In step S109, a winning determination is performed. Here, it is determined that the winning combination is won when a pattern combination corresponding to some winning combination is displayed on the activated winning line 114. For example, if there are "watermelon-watermelon-watermelon" on the validated winning line 114, it is determined that the watermelon has been won. In addition, the flag indicating the internal winning of each winning combination is reset.

  In step S110, if any winning combination with payout is won, the number of medals corresponding to the winning combination is paid out. In step S111, the display corresponding to the winning combination is displayed on the LCD 180, or a sound is output from the sound hole 160, thereby producing an effect that excites the game. In step S112, a game state update process can be executed. In this process, control for changing the type of game is performed. For example, in the case of a bonus winning such as a big bonus (BB) or a regular bonus (RB), a corresponding bonus game can be started from the next time. Prepare the final game so that the normal game can be started from the next time. As described above, one game is completed, and thereafter, the process proceeds by returning to step S101 and repeating the above-described processing.

<Start operation acceptance / random number acquisition processing>
Next, the start operation acceptance / random number acquisition process of S102 will be described with reference to FIG. FIG. 9 is a flowchart of the start operation acceptance / random number acquisition process in S102. In S131, the flashing of the light emitting unit 210a of the start lever sensor 210 is started. In the present embodiment, it is assumed that the start lever sensor control unit 333 generates a driving pulse for blinking the light emitting unit 210a and outputs the driving pulse to the light emitting unit 210a according to a command from the Main CPU 310. You may make it produce | generate like wear.

  In S132, it is determined whether or not a start operation detection signal is output from the light receiving unit 210b of the start lever sensor 210. If applicable, the process proceeds to S133, and if not applicable, the process waits. In S133, the light emitting unit 210a stops blinking and is turned off. In S134, a random value is acquired from the random number generation circuit 311. The random value acquired here is a random value latched at the time of the detection signal of the start operation. In S135, the rotation of all reels 110 to 112 is started substantially simultaneously. The process ends as described above.

Second Embodiment
In the first embodiment, the start operation is detected at the timing when the light emitting unit 210a emits light for the first time with the start operation performed on the start lever 201, but the light emitting unit is operated with the start operation performed. The random number is determined on the assumption that the start operation is detected when the number of blinks 210a (the number of blinks coincides with the number of times the light receiving unit 210b switches from the non-light-receiving state to the light-receiving state) reaches a preset number of times. Yes.

  FIG. 10 is a timing chart illustrating the principle of how the start lever sensor 210 detects the start operation in this embodiment, in other words, at what timing the random number value is determined. 10, (a) is a clock signal transmitted from the crystal oscillator of the random number generation circuit 311, (b) is a timing chart of numerical value update of the random number generation circuit 311 (synchronized with the clock signal of FIG. 10 (a)), c) is a drive pulse input from the start lever sensor control unit 333 to the light emitting unit 210a, (d) is an example of sensor output output from the light receiving unit 210b, and (e) is an example of detection timing of the start operation. ing.

  D in FIG. 10 shows the start operation detection timing (random number determination timing) when the set number of times is set to two. When the number of flashes of the light emitting unit 210a is the second time (the first time is C). Will be used for internal lottery. For this reason, the delay time 2 of FIG. 10 can be generated from the timing when the player performs the start operation until the random value is determined. With this configuration, since the random value at the delay time 2 is acquired by the Main CPU 310 after the player operates the start lever 201, it is possible to make cheating more difficult.

  FIG. 11A is a flowchart of the start operation acceptance / random number acquisition process of S102 in the present embodiment. Here, it is assumed that the drive pulse for blinking the light emitting unit 210a is generated by software by the processing of the Main CPU 310, and it is assumed that the start lever sensor control unit 333 simply turns on and off the light emitting unit 210a. Of course, a configuration in which 333 generates a drive pulse can also be employed.

  In S141, the number of flashes of the light emitting unit 210a when the start operation is performed is set. The set number of blinks is set in a blink number counter configured using a predetermined area on the RAM 313. The number of flashes may be a predetermined fixed number, or may be selected and set from a plurality of types for each game. In the latter case, the delay time is more likely to fluctuate, thus preventing fraud. It is effective, especially when it is determined by lottery. FIG. 11B is a diagram showing a lottery probability example of a plurality of types of blinking times, and is an example in which the number of blinking numbers 1 to 4 is set with an equal probability (1/4).

  In S142, the light emitting unit 210a is turned on. In S143, it is determined whether or not it is an operation state switching timing. That is, it is a process for generating a drive pulse for blinking the light emitting unit 210a by software, and the time until switching is measured by the software timer according to the set blinking period, and it can be the time. If not, the process proceeds to S144, and if not, the process proceeds to S145.

  In S144, the light emitting unit 210a is turned off when the light is on, and is turned on when the light is off. In S145, it is determined whether a start operation detection signal is output from the light receiving unit 210b of the start lever sensor 210. If applicable, the process proceeds to S146, and if not, the process returns to S143. In S146, the count value of the blinking number counter is decremented by one. In S147, it is determined whether or not the count value of the blinking number counter is zero. If applicable, the process proceeds to S148, and if not, the process returns to S143.

  In S148, the light emitting unit 210a is turned off. In S149, a random value is acquired from the random number generation circuit 311. The random value acquired here is the random value latched at the time of the last detection signal of the start operation. In S150, the rotation of all reels 110 to 112 is started substantially simultaneously. The process ends as described above.

<Third Embodiment>
In the said 1st and 2nd embodiment, although the case where the blinking period of the light emission part 210a was a fixed period was assumed, you may select and set from several types of period for every game. Further, the blinking cycle may change continuously. Further, the duty cycle may be changed so that the flashing period is constant but the light emission time and the light-off time are different. 12A to 12D are diagrams showing examples of the blinking cycle of the light emitting unit a. (A) and (b) in FIG. 12 have different periods, (c) has a continuously changing blinking period, and (d) has a duty ratio changed so that the light emission time and the turn-off time are different. It is an example. According to these examples, the delay time from the start operation to the start lever 201 to the determination of the random number value can be further varied, and illegal acts can be more effectively prevented.

  FIG. 13 is a flowchart of the start operation acceptance / random number acquisition process in S102 when the blinking cycle of the light emitting unit 210a is selected and set from a plurality of types of cycles (for example, FIGS. 12A to 12C). It is. Here, a case where the drive pulse for blinking the light emitting unit 210a is generated by software by the processing of the Main CPU 310, but the start lever sensor control unit 333 may generate the drive pulse.

  In S161, the blinking cycle of the light emitting unit 210a is set. The blinking cycle can be selected and set by lottery. In S162, the light emitting unit 210a is turned on. In S163, it is determined whether or not it is the operation state switching timing. That is, it is a process for generating a drive pulse for blinking the light emitting unit 210a in software, and according to the blinking period set in S161, the time until switching is measured by the software timer, If so, the process proceeds to S164, and if not, the process proceeds to S165.

  In S164, the light emitting unit 210a is turned off when the light is on, and is turned on when the light is off. In S165, it is determined whether or not a detection signal for the start operation is output from the light receiving unit 210b of the start lever sensor 210. If applicable, the process proceeds to S166, and if not, the process returns to S163. In S166, the light emitting unit 210a is turned off. In S167, a random value is acquired from the random number generation circuit 311. The random value acquired here is a random value latched at the time of the detection signal of the start operation. In S168, the rotation of all reels 110 to 112 is started substantially simultaneously. The process ends as described above. It should be noted that the third embodiment and the second embodiment can be combined by incorporating the blinking cycle setting process (S161) at the beginning of the process of FIG.

<Fourth embodiment>
In each of the above embodiments, when the start lever 201 is in the neutral position, that is, when it is not operated, the light blocking member 201c blocks the light from the light emitting unit 210a so that the light receiving unit 210b cannot receive light, and the start operation is performed. In this case, the light blocking member 201c is moved so that the light receiving unit 210b can receive light from the light emitting unit 210a. 14A is a schematic cross-sectional view showing the structure of the start lever unit 200 in the case of the reverse configuration (when not operated), and FIG. 14B is a schematic cross-sectional view showing the structure of the start lever unit 200. During operation).

  2 is different from that shown in FIG. 2 in that the light shielding member 201c ′ is U-shaped, and the light from the light emitting unit 210a is received when the start lever 201 is in the neutral position, that is, when not in operation. When the start operation is performed, the light shielding member 201c ′ moves and the light shielding member 201c ′ shields the light from the light emitting unit 210a so that the light receiving unit 210b cannot receive light.

  Next, FIG. 15 is a diagram exemplarily showing the circuit configuration of the random number generation circuit 311 in the fourth embodiment, which is different from the example of FIG. 3 in that the latch signal is started from the start lever sensor 210. The detection signal (START in FIG. 3) is replaced with a drive pulse for the light emitting unit 210a.

  Next, FIG. 16 is a timing chart illustrating how the start lever sensor 210 detects the start operation in this embodiment, and its detection principle. 16, (a) is a clock signal transmitted from the crystal oscillator of the random number generation circuit 311, (b) is a timing chart of numerical value update of the random number generation circuit 311 (synchronized with the clock signal of FIG. 16 (a)), ( c) is a drive pulse input from the start lever sensor control unit 333 to the light emitting unit 210a, (d) is an example of sensor output output from the light receiving unit 210b, and (e) is an example of detection timing of the start operation. ing.

  In this embodiment, when the start operation is not performed on the start lever 201, when the light emitting unit 210a is turned on (detectable state), the light receiving unit 210b detects this. Further, when the light emitting unit 210a is turned off (non-detection state), the light receiving unit 210b is not receiving light. Therefore, the blinking of the light emitting unit 210a appears as it is in the detection result of the light receiving unit 210b.

  If a start operation is performed on the start lever 201 while the light emitting unit 210a is blinking, light from the light emitting unit 210a is blocked by the light blocking member 201c 'and is not detected by the light receiving unit 210b. Therefore, even if the light emitting unit 210a is turned on, the light receiving unit 210b indicates non-light reception. Therefore, the start operation is performed when the light emitting unit 210a is turned on and the light receiving unit 210b is not receiving light. That is, the Main CPU 310 acquires a random value determined when the light receiving unit 210b does not receive light from the light emitting unit 210a when the light emitting unit 210a is turned on.

  In FIG. 16, when the start operation for the start lever 201 can be accepted, the light emitting unit 210a starts blinking (FIG. 16C). The detection signal of the light receiving unit 210b has the same waveform as the blinking of the light emitting unit 210a as shown in FIG. On the other hand, when a start operation is performed on the start lever 201 (A in FIG. 16), the light receiving unit 210b enters a non-light receiving state, and the light receiving unit 210b does not receive light even when the light emitting unit 210a is turned on (B in FIG. 16). At this time, the start operation is detected. For this reason, the delay time of FIG. 16 can be generated from the timing when the player performs the start operation until the start operation is detected. This can prevent fraud.

  FIG. 17 is a flowchart of the start operation acceptance / random number acquisition process of S102 in the present embodiment. Here, a case where the drive pulse for blinking the light emitting unit 210a is generated by software by the processing of the Main CPU 310, but the start lever sensor control unit 333 may generate the drive pulse.

  In S171, the light emitting unit 210a is turned on. In S172, it is determined whether or not it is an operation state switching timing. That is, it is a process for generating a drive pulse for blinking the light emitting unit 210a in software, and the time until switching is measured by the software timer according to the set blinking period, and when that time is reached, S173 If not, the process proceeds to S174.

  In S173, the light emitting unit 210a is turned off when the light is on, and is turned on when the light is off. In S174, it is determined whether or not a start operation detection signal is output from the light receiving unit 210b of the start lever sensor 210. If applicable, the process proceeds to S175, and if not, the process returns to S172. In S175, it is determined whether or not the light emitting unit 210a is being lit. If this is the case, the light-emitting unit 210a is lit but the light-receiving unit 210b is not receiving this light, and the process proceeds to S176 because there is a start operation. If not applicable, the process returns to S172. In S177, a random value is acquired from the random number generation circuit 311. The random value acquired here is a random value latched by the drive pulse of the light emitting unit 210a when the start operation is detected. In S178, rotation of all reels 110 to 112 is started substantially simultaneously. The process ends as described above. This embodiment can be combined with the second and third embodiments, but when combined with the second embodiment, the light receiving unit 210b is not receiving light from the light emitting unit 210a. A random value is determined when the number of blinks of the light emitting unit 210a reaches a preset number of times.

<Fifth Embodiment>
In each of the above embodiments, one start lever sensor 210 is provided. However, since the player can tilt the start lever 201 up and down, the start operation when the operation portion 201a of the start lever 201 is pressed down is provided. In addition, a plurality (two) of start lever sensors 210 that respectively detect the start operation when pressed upward can be provided.

  FIG. 18 is a perspective view of the start lever unit 200 ′ in the present embodiment. The difference from the start lever unit 200 shown in FIG. 2A will be described. The start lever sensors 210A and 210B are configured in two stages in the vertical direction, and the width in the vertical direction of the light shielding member 201c 'is slightly wider.

  In the present embodiment, when the start lever 201 is in the neutral state, the light blocking member 201c 'is in a position where both light receiving portions of the start lever sensors 210A and 210B block the light from the light emitting portion so as not to receive light. When the operation unit 201a is pressed downward and a start operation is performed, the light shielding member 201c ′ is interposed between the light emitting unit and the light receiving unit of the upper start lever sensor 210A, but the light emitting unit of the lower start lever sensor 210B— Without being interposed between the light receiving parts, the light receiving part of the start lever sensor 210B can receive light. When the operation unit 201a is pressed upward and a start operation is performed, the light shielding member 201c ′ is interposed between the light emitting unit and the light receiving unit of the lower start lever sensor 210B, but the light emission of the upper start lever sensor 210A. The light receiving part of the start lever sensor 210A is in a state capable of receiving light without being interposed between the light receiving part and the light receiving part.

  In the case of this embodiment, each start lever sensor 210A and 210B is provided with a start lever sensor control unit 333 so that the blinking period can be individually set. The output of the light receiving unit of each start lever sensor 210A and 210B is an OR circuit. This is input to the random number generation circuit 311 and used as a latch signal for the random number value.

  Next, FIG. 19 is a timing chart illustrating how the start lever sensors 210A and 210B detect the start operation in this embodiment, and the detection principle thereof. 19, (a) is a drive pulse supplied to the light emitting part of the start lever sensor 210A, (b) is a drive pulse supplied to the light emitting part of the start lever sensor B, and (c) is a detection timing of the start operation. Each example is shown.

  First, when a start operation for the start lever 201 can be accepted, drive pulses having different blinking cycles are supplied to the start lever sensors 210A and 210B. Next, when a start operation is performed on the start lever 201 (A in FIG. 19), when the operation unit 201a is pressed downward, the timing of B1 in FIG. 19, that is, the drive pulse of the start lever sensor 210A is detected. A start operation is detected at the rising edge, and a random value is determined. On the other hand, when the operation unit 201a is pressed upward, the start operation is detected at the timing of B2 in FIG. 19, that is, the rising edge of the drive pulse of the start lever sensor 210B, and the random value is determined. Since the delay time varies depending on how the start lever 201 is started, and different random numbers are used, illegal acts can be further prevented.

<Sixth Embodiment>
In each of the above embodiments, a light sensor of a type in which the light emitting unit and the light receiving unit face each other and the light shielding member passes through the slit is used as the start lever sensor, but a reflection type photo sensor can also be employed. FIG. 20A is a perspective view of the start lever unit 1200 when a reflection type optical sensor is employed.

  The start lever unit 1200 includes a start lever 1201, a support frame 1206 that supports the start lever 1201, and detection means that detects a start operation with respect to the start lever 1201, and a start lever sensor 1210 that is a reflective optical sensor. Prepare. The start lever 1201 is provided at one end of the spherical operation unit 1201a operated by the player and the other end, and the start lever sensor 1210 detects the start operation. A reflection member 1201c, and a movable shaft 201b that couples the operation unit 1201a and the reflection member 1201c.

  The support frame 1206 is formed in a substantially cylindrical shape so that the movable shaft 1201b of the start lever 1201 can be inserted therethrough, and includes a shaft body 1207 that passes through the movable shaft 1201b so as to be orthogonal to the movable shaft 1201b. It is supported so as to be rotatable around 1207.

  The difference from the start lever unit 200 described above is that the start lever sensor 1210 is a reflective optical sensor, and the light emitted from the light emitting unit 1210a is emitted toward the reflecting member 1201c of the start lever 1201 in a neutral state, and receives light. The light receiving surface of the portion 1210b is arranged so as to face the reflecting member 1201c of the start lever 1201 in a neutral state. The reflecting member 1201c has a smooth end surface so that the light from the light emitting portion 1210a is reflected and guided to the light receiving portion 1210b, and a mirror surface or the like is formed.

  In the configuration of FIG. 20A, when the start lever 1201 is not operated (neutral state), the light receiving unit 1210b can receive light from the light emitting unit 1210a, the start operation is performed, and the start lever 1201 rotates. When the reflecting member 1201c moves, the light from the light receiving unit 1210b is not reflected by the reflecting member 1201c, and the light receiving unit 1210b enters a non-light receiving state. Of course, it is also possible to configure in the reverse form.

<Seventh embodiment>
In each of the above embodiments, the start lever sensor control unit 333 is configured in the main control unit 300. However, the start lever sensor control unit 333 may be mounted on the start lever unit to be unitized. FIG. 20B is a perspective view of the start lever unit 2200 of the present embodiment.

  The start lever unit 2200 includes a start lever 2201, a support frame 2206 that supports the start lever 2201, a support frame 2206, a base body 2220 that forms an attachment to the slot machine 100, a start lever sensor 2210, A start lever sensor 2210 is mounted, and includes a control circuit board 2222 (corresponding to the start lever sensor control unit 333) that controls the start lever sensor 2210, a support frame 2221 that supports the start lever sensor 2210, the control circuit board 2222, and a base body A support frame 2206 is mounted on the front side of 2220 and a support frame 2221 is mounted on the rear side to form a unit.

  The start lever 2201 is provided at one end of the spherical operation unit 1201a operated by the player and the other end, and the start lever sensor 2210 detects the start operation. A light shielding member 2201c, and a first movable shaft 2201b that couples the operation unit 2201a and the light shielding member 2201c.

  The support frame 2206 is formed in a substantially cylindrical shape so that the movable shaft 2201b of the start lever 2201 can be inserted therethrough, and supports the start lever 2201 so that the start lever 2201 can tilt in any direction. The base body 2220 is formed in a substantially cylindrical shape, and a light shielding member 2201c is inserted in the rear end portion thereof, and includes a slit portion 2220a for guiding the vertical movement thereof. The start lever 2201 is supported by the support frame 2206 so that it can be tilted in any direction. However, the moving direction of the light shielding member 2201c is restricted by the slit portion 2220 and can be tilted only in the vertical direction.

  The control circuit board 2222 controls the light emitting unit of the start lever sensor 210 to alternately change the operation state between a detectable state where the start operation can be detected and a non-detected state where the start operation is not detected. Here, the blinking control of the light emitting unit is performed. The control circuit board 2222 is provided with an input terminal for receiving a command from the Main CPU 310, an output terminal for outputting an output signal of the light receiving unit of the start lever sensor 210, and the like. In the case of the present embodiment, it is assumed that the drive pulse for blinking the light emitting unit of the start lever sensor 210 is generated by the control circuit board 2222, and the Main CPU 310 instructs the control circuit board 2222 to start and stop blinking. Will do. By providing the control circuit board 2222 in the start lever unit 2200 as in the present embodiment as a unit, it is possible to apply the above-described measures against fraud without almost changing the slot machine with the existing specifications. it can.
